Given below are two statements:
Statement I: Flood fringe is the lowest part of the flood plain, where no development is permitted and which is reserved for the passage of flood flows.
Statement II: Floodway is an area of floodplain land where filling and development may be permitted subject to land use and building code regulations designed to minimize damage.
In the light of the above statement, choose the correct answer from the options given below:
Both Statement I and Statement II are false
To determine the correctness of the given statements, we need to understand the concepts of "flood fringe" and "floodway" as they relate to floodplain management.
Flood Fringe: This is the portion of the floodplain that lies outside the floodway. It is typically the area where development may be allowed with certain restrictions or provisions, like elevating structures above the base flood elevation. It is not solely reserved for the passage of floodwaters.
Floodway: This is the central part of a river's floodplain, where floodwaters are primarily located during a major flood. The floodway is maintained to carry floodwaters and prevent blockages, so strict regulations typically restrict development in this area to minimize the risk of damage and prevent increased flooding elsewhere.
Based on these definitions, let's evaluate the statements:
Since both statements misrepresent the definitions and typical management practices regarding flood fringe and floodway, the correct answer is:
Both Statement I and Statement II are false.
Thus, the conclusion reinforces that understanding the precise definitions and uses of floodplain areas is crucial for correctly interpreting exam statements. To correctly answer such questions, one should be well-versed with specific environmental management terminologies and their applications.
